â€œThe firearm was detected on Friday at the security checkpoint when a TSA employee underwent screening at the beginning of their shift,â€� Transportation Security Administration spokesman Mike McCarthy told WBZ-TV.

â€œThe firearm was located in a sort of â€˜lunchpail,â€™ where the individual had packed a meal in a sort of backpack,â€� McCarthy said.

Authorities interviewed the unnamed employee, who said the gun was mistakenly packed with theÂ lunch.Â Londonderry police didn’t respond to the Union Leader’s request for the worker’s name. It wasn’t immediately clear, based on reports, whether the firearm was loaded or not.
